signs and letters used in music in the position which they ought to occupy on the various staves, the printing bcin made on the staff, including the upper and ower lines.

In the majority of nown tytpewriting machines the same set of the eys serves to print the letters of the two fonts and the various si ns, each lever carrying two characters an the paper carriage being subjected at the proper moment to a vertical or horizontal isplacement for. printing the capitals and certain signs.

In a machme constructed according to this invention, which is for the purpose of printing music, while at the same time capale of serving as 'an ordinary typewriter, the parts are arranged in such a manner that instead of displacing a roller the frame carrying the whole of the printing keys is displaced accordingly as the machine is to be used for printing music or for printing the characters ofthe alphabet. By displacing the whole of the keys the printin levers are brought into a )osition suitable for imprinting the desired si ns such as the musical notes, or the small letters, or the ca )itals, all of which are arranged correspondingly, so that the paper receives the impression of thekcys as 1t passes the printing point carried by its carriage. When the machine is printing music, it is necessary that the printing point should be upon the appropriate line of the staff. For this purpose the pa )er carriage is so constructed that it can e displaced by the operation of piano keys (that is to say, he s resembling piano keys and arranged exact y like such keys) arranged in front of the ordinarly typewriting keys, each of which piano eys determines exactly the position which the note will have on the staff to which it belongs. The object of oicrating the piano keys, therefore, is to disp ace the paper carriage and'thc paper which it carries, to a suitable degree.

The piano ke ing music, and pressed for imprintin ate piano key must printing point on to staff.

The piano keys, fourteen in number, the intervals for two middle gamuts. upper octave is obtained by the operation of store a typewriter key is dee struck to'bring the the desired place in the a note the approprh s are only used when printas if a cam which depresses the paper .carriae through the interval of an octave, and t e lower octave is obtained by the operation of the same cam raising the paper carria e through the interval of an octave. 'l e movement of the paper up or down for the space of a single note in any octave 1s etfected by means of a keyboard resembling a )or'tion of the keyboard of a piano, as hereinafter explained in detail.

The principle of the invention having been thus an lained, a machine suitable for putting itmto practice will now be described with reference to the accompanying drawm s.

igure 1 is a Fig. 2 is a side side elevation of the machine. elevation of the frame that carries the printing keys. Fig. 3 is a front view of the aft hand end of tiis frame an Fig. 4 is a front view of the right hand end thereof. Figs. 5 and 6 are respectively a front elevation and a plan of the principal parts of a machine comprising the invention. The frame A of the machine has two keyboards, one having keys B similar to those of a piano, and the other keys O analo one to those of an ordinary typewriter. ach of the keys C operates axle a, the ends of which extend through a frame E which supports the whole of this key-board comprising the typewriting keys. This frame E carries an axle b on which are pivoted all the lovers F which carry the various characters, that is to say the mus cal notes c, the small lettered, and the ca itals or other printing sifigns e. The end 0 each lever D is connects with its character lever Fby a link f. When the frame E is inthc position shown in full lines in Fig. 1, t is adapted for ordinar tylpewrit ing, that is. to say the characters wi be printed by opersting the keys. For printing the capitals the rame E is lowered into a position which is not shown. When music is to beprinted the frame is moved into the position shown a lever D centered on an the effect of the spring being limited by the stop 9.

he stop devices shown in F1 s. 2, 3 and 4; serve to keep the frame E in t e two lower positions, that is to say in the positions 1n which the s rin R is more or less stretched and in which ordinary typewriting of the u er and lower case characters is possib e. n each check of the frame A is a bracket h carrying the fulcrum i of a lever which can be turned by a handle'fi': to brin 1t above the flange k on the frame 1. On t e right hand side, Fig. 4, this flange is at a lower-level than that on the left hand side, Fig. 3, and when engaged by the corresponding lever 7' serves to old the frame in the position for typewriting the small letters, the flange on the left hand side being en aged by the corresponding lever 3' when t e capitals are to be printed. In Fig. 4 the lever 51' has been engaged with the lowerfiang e k and this is also the position in Fig. 1, the machine bein thus adapted for printing small letters. hen a large number of capitals has to be printed in succession the frame E is allowed to rise until the fiangeat the left hand end engages a corres onding lever 7'.

he mechanism so far described suffices 'to enable the operation of the keys C to print.

musical notes or ordinary typewriting in two fonts, as may be desired.

At the lower part of frame E there are two bearings for a shaft m upon which are centered levers G connected at the front end by a bar or pedal n, and at the rear end by a shaft 0 which is linked by a rod 0- controllin by any suitable known mechanism the latera advance of the paper carriage. This mechanism has been omitted from the drawing for the sake of clearness. r

. The upward stroke of levers G is limited by the stop rod p. The levers G carry uprights g in which is mounted the rod q const1tuting a support for all the levers D. When any one of the keys C is o erated, the rod g is depressed and with it t 1e levers G, so that the rod 0 which controls the advance of the paper carriage is operated.

The paper carriage comprises two-arms H fixed together by the transverse spindles 'I which are the axles of two rollers J over which the paper to be imprinted passes. The spindles I carry chain wheels K geared together by the chain M. The paper is made rod u in such a manner that they move toon and between the supplementary upper,

The displacement of the and lower lines. cams Q Q may be made easily by hand, the sides of the notches 'v, 1:, 12 being suitably rounded to allow of this displacement without thenecessity of lifting the carriage.

It will be understood that when the rod 8 is engaged in the notches '0, the signs will be printed on the staff. When this red sis restmg in the cam notches '0, whereby the paper will be raised the interval of an octave, the lower octave will be printed after depressing the appropriate one of the seven left-hand keys of the key board. Similarly when the rod s is en aged in the notclies e of the cam, whereby t e paper will be lowered the interval of an octave, the signs of the upper octave will be printed after having depressed the ap ro riate one of the seven keys B of the rig t liand'half of the key-board. For the notes from and beneath the do (key 1 on the left) and for those from and beneath the la (key 13), small supplementary lines should be printed before striking the note. To this end four keys 0 will be providedwith signsforming a lme located more or less apart from the last line of the staff.

The lower edge of the tail of each cam Qbis serrated as at a; and the teeth are engaged y a spring detent S. The detent S insures the cam s moving fully to one or other of its three important ositions, preventing its remaining in posit1on with the rod 8 between two of the notches o, e, '0 This pointed detent is also a safety-catch which holds more surely than the rod .9, The spring T connected with the back of the carriage is for the purpose of balancing the weight of the latter.

It remains to explain how the whole carriage is mounted to allow that line of the staff on which the musical note is to be printed to be brought exactly into line with the printing point for imprinting each note, that is to say into the line .2 indicated in Fig. 1. For this purpose eachv cheek P carries a fork U in which is mounted a roller 7 The two rollers rest on a bar common to both carried in arms X from the shaft O and'this bar V is itself supported on the ends of. two

vertical rods Y, one on each side of the machine, connected with the bar by a pivot 12;

On its lower end each rod carries pivoted to it a bearing for a spindle a. on which turn fourteen rollers (1, this bearing being pivoted to the rod as at c. The joints 1) "0 are for the purpose of allowing'a slight relative deviation of these rods which lift the paper carriage for rinting the musical notes as already speci ed. v

The downward stroke of the. spindle a is limited by two stops on the checks of the frame A, and each of the fourteen rollers d corresponds with one of the keys B which are depressed for the purpose of suitably lifting the paper carriage. All the keys B, whatever may be the note to which each corresponds, have all the same stroke in order to facilitate their manipulation by the fingers, such manipulation being dillicult if the stroke varies with the note represented. For

4 this purpose the levers carrying the keys are centered at different distances from their ends as indicated at e in Fig. 1. Thus the same vertical stroke of a key corresponds with a different stroke for the other end of the lever carrying it. It follows that the roller (1 corresponding with the key depressed is more or less raised suitably with the note in question, and spindle a of the rods Y and the paper carriage resting upon the rod V are corres ondingly differently raised. The keys mar (ed B are black, and are fixed, merely serving to make the iano key-board B resemble that of a normaFkeyboard and to easily recognize the key 1.
